What is another name for a solitary pulmonary nodule?

A solitary pulmonary nodule is often referred to as a "coin lesion" due to its round shape and typically well-defined edges, resembling the size and appearance of a coin on imaging studies such as chest X-rays or CT scans. This term helps differentiate solitary nodules from other pulmonary abnormalities, such as widespread disease or larger masses. The use of the phrase "coin lesion" can also provide a quick visual cue for healthcare professionals when discussing potential diagnoses, risk factors, or treatment options.

In contrast, granulomas are often specific types of nodules that indicate inflammation, typically associated with infections or chronic inflammatory conditions. Mass lesions usually refer to larger areas of abnormalities that could involve malignancy or other serious pathologies and do not specifically denote the small size or solitary nature of a pulmonary nodule. Cystic lesions refer to fluid-filled sacs and are not synonymous with the solid characteristic of a solitary pulmonary nodule. Hence, "coin lesion" is the most accurate alternate name among the choices given.
